Title: Barrier laminate, packaging material using the same, and packed body using the same
Inventor: SEKIGUCHI MAMORU
IPC: C08J7/04
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent barrier properties depending upon a process from changing and deteriorating by a method wherein a covering film, which is produced by forming a thin film layer on a polymer film base material, is laminated through an adhesive having a gas barrier layer onto a heat sealing resin. SOLUTION: A covering film is produced by forming a thin film layer 3 made of metal or metal oxide on one side of a polymer film base material 2. Next, a barrier laminate is produced by bonding the thin film layer, on the surface of which a barrier adhesive 6 is applied, of the covering film 1 having a transparency with a heat sealing resin 7. Through this constitution, minute pin hole parts existing in advance are filled up with an inorganic material super-finely dispersed in a barrier adhesive. Thus, high grade barrier properties are realized. A massive gas transmission through he cracks and fractures, which develop through the expansion and contraction of the film caused at the printing thereon and the lamination of other base material thereon and through the thermal stress due to heat shock, in the thin film layer can be checked by the layer made of the adhesive.

IPC: H01S5/068
Filed: 1982-07-01
Abstract: PURPOSE:To obtain a laser driving circuit, which can always secure a constant light output and an extinction ratio in an usable temperature range and does not have fluctuation in output waveforms, by flowing a bias current, which is varied with the variation in threshold value of laser light due to temperature change, to a semiconductor laser, controlling an input signal that is applied to one of transistors, thereby compensating for quantum efficiency variation due to the temperature change. CONSTITUTION:A CML (current mode logic) circuit is used in a high speed laser driving circuit. A thermistor 24 is inserted in a common emitter circuit. The CML is constituted by transistors 10 and 12 and a resistor 14. Said thermistor 24 has replced a part of the emitter resistor of the CML. A capacitor 26 bypasses an AC component. An input signal Sg is applied to the transistor 10, and a reference voltage Vr is applied to the other transistor 12. The resistances of the fixed resistor 14 and the thermistor 24 are suitably selected so as to obtain Sg>Vr. The current value is set so that it is varied with the temperature when a current is switched from the transistor 12 to the transistor 10. The average light output of a laser 20 is detected, and the signal Sg is adjusted so that the output becomes constant.
